@emtp211 Looks great though it seems like the texture on the roof is a little stretched out and of low quality. By the way, is it possible to remove the huge rambar from this truck and could you make a texture like this but for the special Phantom cab that can also pull the Mobile Operations Trailer?

Yea is the Phantom unlocked? I think its possible. I will be updating an updated version with em lights. Question were you able to get the trailer skin to appear in game. I don't uv map but i will consider removing roof text all together l.

Before i try it out i just got two questions. Is it a replace for the original in-game models & are the trailer and the cab attached as one? Cause i hate how the game treats them as 2 different vehicles and we can't save them at a place using the persistance mods.
